You can include a '''non-breaking space''' (sometimes called '''non-printing character''') where you require two words to always appear together on the same line, such as ''Mr.&nbsp;Smith'' or ''400&nbsp;km/h'' using '''<code>&amp;nbsp;</code>''' in place of a regular space between the two "words" that need to behave as a single word (never be separated on different lines).

=== Special Characters ===

−

−

Symbols and other special characters not available on your keyboard can be inserted through a special sequence of characters. Those sequences are called {{Wpd|List of HTML entities|HTML entities}}. For example, the following sequence (entity) '''&amp;rarr;''' when inserted will be shown as <ins>right arrow</ins> HTML symbol &rarr; and '''&amp;mdash;''' when inserted will be shown as an <ins>em dash</ins> HTML symbol &mdash; .

−

−

{{Tip|Hover over any character below to find out the symbol that produces it. Some symbols not available in the current font will appear as empty squares.}}

*The latter methods of sub/superscripting cannot be used in the most general context, as they rely on Unicode support which may not be present on all users' machines. For the 1-2-3 superscripts, it is nevertheless preferred when possible (as with units of measurement) because most browsers have an easier time formatting lines with it.

'''NUMBEROFARTICLES''' is the number of pages in the main namespace which contain a link and are not a redirect, in other words number of articles, stubs containing a link, and disambiguation pages.

−

−

'''CURRENTMONTHNAMEGEN''' is the genitive (possessive) grammatical form of the month name, as used in some languages; '''CURRENTMONTHNAME''' is the nominative (subject) form, as usually seen in English.

−

−

In languages where it makes a difference, you can use constructs like <nowiki>{{grammar:case|word}}</nowiki> to convert a word from the nominative case to some other case. For example, <nowiki>{{grammar:genitive|{{CURRENTMONTHNAME}}}}</nowiki> means the same as <nowiki>{{CURRENTMONTHNAMEGEN}}</nowiki>. <!-- Is there a reference for this, other than the source code (for example, phase3/languages/Lnaguage*.php) ? -->

Internally, the first letter of the target page is automatically capitalized and spaces are represented as underscores (typing an underscore in the link has the same effect as typing a space, but is not recommended).

Thus the link above is to the URL en.wikipedia.org/wiki/Public_transport, which is the Wikipedia article with the name "Public transport". See also Canonicalization.

A red link is a page that doesn't exist yet, they can be created by clicking on the link.

The part after the number sign (#) must match a section heading on the page. Matches must be exact in terms of spelling, case, and punctuation. Links to non-existent sections are not broken; they are treated as links to the top of the page.

Include "| link title" to create a stylish (piped) link title.

If sections have the same title, add a number to link to any but the first.#Example_section_3 goes to the third section named "Example section".

[[Wikipedia:Manual of Style#Italics]] is a link to a section within another page.

[[#Links and URLs]] is a link to another section on the current page.

[[Wikipedia:Manual of Style#Italics|Italics]] is a piped link to a section within another page.

The server fills in the part after the pipe character (|) when you save the page. The next time you open the edit box you will see the expanded piped link. When previewing your edits, you will not see the expanded form until you press Save and Edit again. The same applies to links to sections within the same page (see previous entry).

The character '''tilde''' (~) is used when adding a comment to a Talk page. You should sign your comment by appending four tildes (~~~~) to the comment so as to add your user name plus date/time: :~~~~Adding three tildes (~~~) will add just your user name:: ~~~and adding five tildes (~~~~~) gives the date/time alone:: ~~~~~

(Redirects)

Redirect one article title to another by placing a directive like the one shown to the right on the first line of the article (such as at a page titled "USA").

#REDIRECT [[United States#History]] will redirect to the [[United States]] page, to the History section, if it exists

(Wikimedia link)

To connect, via interwiki link, to a page on the same subject in another language, put a link of the form: [[language code:Title]] near the bottom of the article. For example, in article "Plankton", which is available on a lot of other wikis, the interwiki link to the German Wikipedia looks like:

A user's '''Contributions''' page can be linked as: [[Special:Contributions/UserName]] or [[Special:Contributions/192.0.2.0]]

(Categorize)

To put an article in a category, place a link like the one to the right anywhere in the article. As with interlanguage links, it does not matter where you put these links while editing as they will always show up in the same place when you save the page, but placement at the end of the edit box is recommended.

[[Category:Character sets]]

(Category page link)

To link to a category page without putting the article into the category, use a colon prefix (":Category") in the link. The formatted text link will appear as: Category:Character sets.

If a URL contains a character not in this list, it should be encoded by using a percent sign (%) followed by the hex code of the character, which can be found in the table of ASCII printable characters. For example, the caret character (^) would be encoded in a URL as %5E.

If the "named" version contains a closing square bracket "]", then you must use the HTML special character syntax, i.e. &#93; otherwise the MediaWiki software will prematurely interpret this as the end of the external link.

There is a class that can be used to remove the arrow image from the external link. It is used in Template:Ref to stop the URL from expanding during printing. It should never be used in the main body of an article. However, there is an exception: wikilinks in Image markup. An example of the markup is as follows:

Link to books using their ISBN. This is preferred to linking to a specific online bookstore, because it gives the reader a choice of vendors. However, if one bookstore or online service provides additional free information, such as table of contents or excerpts from the text, then a link to that source will aid the user and is recommended. ISBN links do not need any extra markup, provided you use one of the indicated formats.

To create a link to Book Sources using alternate text (e.g. the book's title), use the internal link style with the appropriate namespace.

Images

Only images that have been uploaded to Wikipedia can be used. To upload images, use the upload page. You can find the uploaded image on the image list.

Text formatting

Special characters

No or limited formatting

—showing exactly what is being typed
A few different kinds of formatting will tell the Wiki to display things as you typed them — what you see, is what you get!

What it looks like

What you type

<nowiki> tag:

The nowiki tag ignores [[Wiki]] ''markup''.
It reformats text by removing newlines and multiple spaces.
It still interprets special characters: →

<nowiki>

It still interprets special
characters: &rarr;

<pre> tag:

The pre tag ignores [[Wiki]] ''markup''.
It also doesn't reformat text.
It still interprets special characters: →

Leading space:

Leading spaces are another way to preserve formatting.

Putting a space at the beginning of each line
stops the text from being reformatted.
It still interprets Wikimarkup and
special characters: →

Invisible text (comments)

It's uncommon, but on occasion acceptable for notes to other editors ( see MOS ), to add a hidden comment within the text of an article. These comments are only visible when editing or viewing the source of a page. Most comments should go on the appropriate Talk page. The format is to surround the hidden text with and may cover several lines, e.g.:

<!-- An example of hidden comments
This won't be visible except in "edit" mode. -->

Table of contents

When a page has at least four headings, a table of contents (TOC) will appear in front of the first header (after the lead). Putting __TOC__ anywhere forces the TOC to appear at that point (instead of just before the first heading). Putting __NOTOC__ anywhere forces the TOC to disappear. See also Compact TOC for alphabet and year headings.

Templates and Transcluding Pages

Templates are segments of Wiki markup that are meant to be copied automatically ("transcluded") into a page. You add them by putting the template's name in {{double braces}}. It is also possible to transclude other pages by using {{:colon and double braces}}.

There are three pairs of tags that can be used in Wikitext to control how transclusion affects parts of a template or article. They determine whether or not wikitext renders, either in its own article, which we will call "here", or in another article where it is transcluded, which we will call "there".

<noinclude>: the content will not be rendered there. These tags have no effect here.

<includeonly>: the content will render only there, and will not render here (like Invisible ink made visible by means of transclusion).

<onlyinclude>: the content will render here and will render there, but it will only render there what is between these tags.

There can be several such section "elements". Also, they can be nested. All possible renderings are achievable. For example, to render there one or more sections of the page here use <onlyinclude> tags. To append text there, wrap the addition in <includeonly> tags above, within, or below the section. To omit portions of the section, nest <noinclude> tags within it.

If a page is transcluded without transclusion markup, it may cause an unintentional categorization. Any page transcluding it will contain the same category as the original page. Wrap the category markup with <noinclude> tags to prevent incorrect categorization.

Some templates take parameters, as well, which you separate with the pipe character.

This template takes two parameters, and
creates underlined text with a hover box
for many modern browsers supporting CSS:
{{H:title|This is the hover text|
Hover your mouse over this text}}
Go to this page to see the H:title template
itself: {{tl|H:title}}
